The present invention relates to a method of tying ribbon, tape or thelike into bows or knots.

The principal object of the present invention is to simplify and thusfacilitate the manner of making bows or knots, and more particularly,but not exclusively, ornamental bows or knots attached to cardboard orthe like, such as greeting cards.

Another object is a new method of making at will either single-1ooped ordouble-looped bows.

still another object is to decrease the length of ribbon or tape neededfor tying the bow or knot.

A further object of the invention is to make a bow or knot attached tocardboard, for example a calendar, in such a manner that part of thetape can be employed for suspending the cardboard or the like.

Other objects of the invention will become clear from the specificationas its proceeds.

In the drawings:

Fig. 1 illustrates an object to be provided with a ribbon tied into aknot or bow.

Figs. 2-14 illustrate steps in a method of making a bow.

Fig. 15 illustrates a modification of the method.

Figs. 16, 17 and 18 illustrate a method of tying a ribbon into a knotwithout a bow.

Figs. 19 and 20 illustrate a method of making a double bow.

Figs. 21-23 illustrate a method of making a bow provided with asuspension loop.

Fig. 24 illustrates an article provided with a bow according to theinvention.

An essential feature of the present invention resides in the fact thatthe bow is made by formin a slip knot, but without a preliminary knot,from a flat ribbon or tape wound around a portion of cardboard or othermaterial, the width of which is essentially not greater than the widthof the ribbon or tape.

If the bow to be made is required as a separate article for subsequentattachment to an object such as a greeting card, calendar or the like,the

aforesaid portion of cardboard or other material may be employed merelyas a former on which to tie the bow, and is subsequently removed.Alternatively, however, the portion of material around which the ribbonor tape is wound may form part of a cardboard or like sheet I (Fig. 1)

used in the production of, for instance, a greeting card, this portionof material, denoted by reference 20, being defined by two parallelslits 2, 3 side by side in the sheet I, which are each of a length notless than the width of the ribbon or tape and the distance between theslits being essentially not greater than said width.

Although for the purpose of explaini g the invention, the parallel slits2, 3 are shown and will be referred to, it is not essential for theperformance of the invention that these slits be parallel, or even thatboth apertu es out in the sheet I shall be slits. The formation of a bowas later to be described can equally well be accomplished with a sheet Ihaving two slits inclined to each other therein or having one littogether with a circular or other suitably shaped hole in place of theother slit.

Referring now particularly to the drawings,

7 Figs. 2 and 3 illustrate various elements of mechanism in their homepositions at the commencement of operations for making a bow. 4indicates a slide the purpose of which will be explained below; 5indicates pliers or pincers for eventually gripping the ribbon or tape 6which may be stored on a spool .(not shown). Shears l are provided foreventually severing a length of the ribbon or tape. 8 and 9 indicateguides for the tape, the ribbon 6 being gripped at the commencementofoperations by the guide 8 with a part 6' of the ribbon protruding from.the upper end of the guide.

The next step in making the bow is illustrated in Figs. 4 and 5. Theguide 8 for the ribbon or tape 5 has been moved through the open shearsI and the slit 2 of the cardboard sheet I, the free end of the tape 6being gripped by the .pincers 5.

In Fig, 6 the guide 8 has been moved down again, the shears l have beenclosed and have out off a length 60 from the ribbon or tape 6.

In Fig. '7, the slide 4 has moved to the right, thereby bending thelower end 6! of the length of tape 60 to the right so as to lie flatagainst the lower side of the sheet I. 50 indicates a second pair ofpincers in a position opposite to slit 3 (not shown for the sake ofsimplicity in the previous fi ures).

In Fig, 8 the second guide 9 has been moved upwards through slit 3 sothat the pincers 50, on closing, grip the end 6! of the length 60. I0indicates a hook (not shown for the sake of simplicity in the previousfigures).

Figs. 9 and 10 illustrate the next step in making the bow in differentviews corresponding respectively to the views shown in Figs. 2 and 3.The pincers 5 have started their movement around the pincers 50, thehook It being turned upwards.

In Fig. 11 the pincers 5 have completed their movement around thepincers 59 so that the length 60 or the ribbon gripped by pincers 5 ismaterial.

wound around its end 6| gripped by pincers D. The hook it; has beenturned through an angle of 180 to hook the length 69.

In Fig. 12 the hook Ill has moved to the right (the pincers 5 followingthis movement) so as to form a loop.

In the position illustrated in Fig. 13, the hook has been turned through90 so that the bow lies fiat against the sheet I and the pliers 5 and 58have been moved to the left so as to tie the bow firmly.

Fig. 14 is a plan view corresponding to Fig. 13. It will be seen fromFig. 14 that the bow made is a single bow which lies in the maindirection of slits 2 and 3 (Fig. l) the length 60 of the ribbon or tapelies in the opposite direction, whereas its end BI is slightly diverted.

Alternatively, the hook when in the position shown in Fig. 12 may beturned through 90 in a direction opposite to that illustrated in Fig.14. In this case, the hook l0 and the bow assume the positionillustrated in Fig. 15, the pincers 5 and 59 being moved so as to assumefinally the position shown in Fig. 15. The bow made in this way isslightly different from that illustrated in Fig. 14, its appearance as awhole being somewhat neater, and the length 60 of the tape and its end6| do not diverge to the same degree as shown in Fig. 14.

From the foregoing it will be appreciated that the bow forms part of asliding knot without preliminary knot.

A simple experiment will show that if the distance between the slits 2and 3 is greater than the width of the ribbon or tape 6, the knot willwork loose. When, however, the said distance is substantially equal toor even less than the width of the ribbon, the knot will not work loosesince the tape is crumpled at the knot and there is thus enough frictionto keep the knot tight.

Figs. 16, 1'7 and 18 illustrate how a knot instead of a bow may be made.Fig. 16 corresponds substantially to Fig. 14, the only difference beingthat the bow engaged by the hook l0 and the length 60 of the tape andits free end 6| are all smaller than the corresponding parts shown inFig. 14. This can be achieved by arranging the pincers 5 and 50 closerto the sheet 1 than illustrated in the previous figures. Referring toFig. 17, the pincers 5 have released their grip on the length 60 of theribbon or tape and the hook Hi has been moved to the right so that thebow shown in Fig. 16 has been opened. In Fig. 18, the pincers 50 havealso been opened and thus released the free end 6|. moved still fartherto the right, the knot being completed.

It will be appreciated that instead of forming a bow or knot by pullingthe ends of a length of tape through two slits in a cardboard, the

knot (or sliding knot in the case of a bow) may be formed simply arounda small portion of When the bow or knot has been formed, the portion ofmaterial may be removed from the bow or'knot; afterwards the bow or knotmay be finally tightened.

Figs. 19 and serve to illustrate how a double bow can be made.

Fig. 19 corresponds substantially to Fig. 8,

the only difference being that in Fig. 19 the end 51 of the length 60 ofthe ribbon or tape is longer than that of Fig. 8, so that when the guide9 has pushed the end 6| into the pincers 50, this end is folded aroundthe guide 9 and part of it is still held by the slide 4 against thelower side The hook It! has been 1,

said fold.

of the sheet I. In this way, the second bow is prepared. The furthersteps of making a double bow correspond to those previously explained inconnection with Figs. 9-14. Fig. 20 corresponds substantially to Fig.14, the only difierence being that the end 61 held by pincers forms abow as well, the end of this second bow lying still underneath thesheet. If desired, it may be pulled up when the double bow is completed.

Figs. 21, 22, and 23 illustrate the formation of an additional loop, forexample, for suspending the cardboard or other sheet when the bow orknot is made. Fig. 21 corresponds substantially to Fig. 8, thedifference being that a small rod or the like II is provided aroundwhich the length is turned before passing its end 6i through the hole 3to form a loop IS. A bow or knot may now be formed as explained above.When the bow or knot is finished, the rod H is moved from its initialposition H as indicated by the arrow (Fig. 22), so that the loop formedbelow the sheet I lies against it. This loop is fastened to the surfaceof the cardboard by any suitable means, for example, a piece of gurnmedpaper 12 stuck so as to cover the slits 2 and 3 and to fix the bow orknot and the loop in their final position. Fig. 23 correspondssubstantially to Fig. 14, but showing the loop [5 still held in positionby the rod Ii.

Fig. 24 shows in perspective view a greetings card or the likecomprising a single-folded cardboard. wrapper a and an insert 1). Thewrapper a and the insert b each possess two parallel slits c and 01,through which a length of ribbon e is drawn. The length of ribbon istied in a slip knot without a preliminary knot, forming a bow Jandattaching the insert 1) to the folded wrapper a, the distancesbetween the slits c and d being at most equal to the width of the ribbone. The length of the slits is equal to or somewhat greater than thewidth of the ribbon e. In the embodiment illustrated, the slits areparallel to the fold g of the folded wrapper, but it is obvious thatalternatively they may be inclined to Instead of providing two parallelslits on both the cardboard and the insert, the slits may be inclined toeach other. Again, instead of providing two slits on both the wrapperand insert, one slit and an opening, for example of circular shape, maybe provided, in which case the distance between each slit and itsassociated opening is at most equal to the Width of the ribbon.

While we have illustrated and described in detail certain preferredforms of our invention. it is to be clearly understood that changes maybe made therein, and we therefore do not desire to limit ourselves tothe specific methods described above, but intend to cover our inventionbroadly in whatever form its principle may be utilised.
